Abstract

USB (Universal Serial Bus) as a computer peripheral bus standards, is a flexible and efficient bus interface. The new version of USB3.0 theoretical transfer speed is up to 5.0Gbit/s, which greatly increases the data transfer bandwidth while retaining its inherent advantages. It’s very suitable for high-speed data acquisition field. But in the actual use of that, data transfer speed is limited that USB devices can’t meet the actual requirements. In this paper, we designed the firmware of the controller to give full play to the characteristics of the chip by using GPIF II digital transmission mode and establishing an automatic DMA channel, thereby improving the actual data transfer rate. Test results show that the real effective transfer rate is up to 350 Mbyte/s, greatly reducing the transfer time.
